Transmitter Channel
The
Two Transmitters cannot operate on the same channel un- less separated by 300 feet (91 m) or more (which is the aver- age maximum operating range). If two transmitters are operating on the same channel inside this perimeter, the re- ceivers will pick up the FM signal of both transmitters, caus- ing a squealing sound to be heard.
Antenna
The transmitter uses a flexible wire “trailing” antenna that is permanently attached to comply with FCC Part 15 Rules. Do not cut or lengthen the antenna. Do not coil the antenna and place in your pocket. This is a tuned antenna and modifica- tion will shorten the range.
Audio Input
There are 2 audio input jacks on the transmitter. One is the Auxiliary input designed to allow audio devices such as teachers aids or tape players to be used. The input jack is a 1/8 inch (3.5mm) stereo/mono jack. Typical input level is 100 mV RMS maximum for normal modulation. More than this in- put will cause the audio to “limit” which may sound unnatural. Reduce the input level, if this should happen, by turning down the input device.
